v5.3: No wake, snow or spray effects. What gives?

[Rallymodeller]

As the title says. The wake, snow and spray effects have stopped showing up in the sim. What confuses me is the effects are still present in the Effects folder. Anyone have any idea? I noticed them missing after I installed the AH DC-3/C-47, but that may be a coincidence.

Apologies for digressing, but you may be able to assist me with a different issue.
You mentioned the AH DC-3.
Could you load up the Florida Air Cargo livery & check what I have written below & advise if the livery is 'normal', or 'sparkly', in your set up. I am wondering if it is a Graphics or Lighting or 'PBR' setting thing?
Thank you

"I had this in P3D v5.2 HF1 & hoped moving to v5.3 HF1 would fix it, but it hasn't.
I have the latest version of the AH DC-3 for P3D v5+ & what appears to be the rivet lines 'sparkle/shimmer' unnaturally, in daytime & at night, per the attached screenshot. (Not just on 1 livery) [on the fin & above the words 'Air Cargo', in particular]
Anyone else had this, have an idea what is causing it, how to fix it?"
